982,467. no Drawin Application filed December 2, 190a: flerlal To all whom it may concern I Be it known that I, Jsquus Euwm BRAN- nunnnnoun, a Swiss citizen, and. resident of Thaon-les' :Vosges, France, have invented new and useful Improvements in Gofl'ered Articles Made from Cellulose Films, which improvements are fully set forth in the following spe'cification.

his invention relates to gofi'ered articles and methods of making the same, and particularly to the production; of golfer-ed or are capable of regenerating embossed cellulose films obtained from aqueous solutions of cellulose.

Aglueous solutions of cellulose, such as xan ogenat'e or ammonio-cuprous solutions,

V this body in physical and chemical condi ions such that the material affects the special form of a transparent ,or opaquefilm, either colored or not, "andof athickness varying between one-hundredth of a millimeter and two eters or more, according to' the mechanicalprocess employed. In this plastic form, the cellulose lends itself to novel and numerous applications, as hereinafter described.

In accordance with this invention a cellulose film-regenerated from a xanthogenate I solubilizing oxidized if desired, or

'or onio-cuprous solution-is gofi'ered or embossed in any desired manner and the depressions filled up with a plastic or ri 'd' reinforcing-material. Compositions suita le for this urpose are preferably composed of mastic o a soft or firm consistency with a base such as resin, india-rubber, or guttapercha, to which may 'be added linseed oil,

gelatin with or without glycerin. Loading agents maybe added such as talc, kaolin, cork, v mal fibers, saw-dust or the hke and coloring matter if desired. The filling material may be' owdered or pressed in th fiber by by machine. The 'film th treated is provided "with a final support to which dry or moist films; dextrin, or glue either mixed with glycerin an inagents or not, alkaline silicate or a ueous solutions of viscose or the like.

e glues or adhesives that can be employed for the dry film onl are alcohol,

chloroform, ether, and car id varnishes,

such as mineral oil varnishes and resin varnishes, fat gummy varnishes, such as lin-.

seed 011 vamish' alone or combined with tyfiographic means, by means 0 'r0 table or ani- 1t is made to adhere by means of an 'adhe- 'sive. The following adhesives are suitable resins, solutions of cellulose in the others, alcohols, acetone, chloroform, such as coll0 dion, solutions of celluloid, actetate of cellulose, etc.-' These various adhesives are em-' ployed inaccordance, with the nature of the supports and of the effects that it is desired to obtain. As supports particularly suited to this operation, paper, cardboard, fabrics of; all kinds, leather, wood, metals in the form of sheets andall bodies presenting a continuous surface maybe cited.-

c The supports may be either white or tinted, colored uniformly or provided with diversely colored designs, entirely or partially metallizedwith a view to obtaining special transparency efl'ects.

A final, support can be applied to the products obtained in this manner after the pouring of the mastic by using the mastic itself as the adhesive agent; 1t should be clearly understood that all the substances enumerated above are included under the term su ports. The employed may be transparent, 0 opaque, colored or colorless. On its front or back orv upon both its faces the film may be painted, impressed by lithographic or engraved ers, transfer processes or any other appro riate means 1n one or more colors.

v hen the cellulose is being regenerated,- it may be .loaded with bodies of all kinds such 'as talc, kaolin, mica, glass and generally speakin substances in t beads or in any other given form, which results in novel effects w1th a ,view to novel applications.

e form of powder, lamellaa,

nstead of embossing thefilm, and i a lyin it (1 or moist to a support, as a ve d scribe the film may be applied to its support, embossed, then filled in the manner described, and then providediwith a secondsupport.

What I claim is 1. An articleof the character described, co isting of a gofiered cellulose film having the de ressions of the go'fiering filled wit a re' orcing material and a supporting surfaceifor the film. p v 2. v article of the character described, a goiferedqcellulose film and e epressions in the gofiering be" ing ed with areinforcing material.

'3. An article of the character described of a gotfered cellulose film and consisting of ,backi ,th d

all minerals and vegetable 90.

backing, the depressions in the gofiering being filled with a reinforcing material and a supporting surface.

d. Anarticle of the character described, 5 consisting of a gofi'ered "cellulose film and backing, the depressions in the goflering being filled with a plastic material which is normallyhard.

5.- An article of the character, described, 10 consisting 01E a gofiered cellulose film and backing, the depressions in the golfering being filled with a plasticmaterial which is normally hard, and a-supporting surface.

In testimony whereof I have signed this specification in the presence of two sub- 15 scribing witnesses. o
